nu'roxonnn vacuum cnnmma 7 concern Be it known that I, EDWARD L. RAY, a

citizen of the United States, residing at Hedrick, in the'county ofKeokuk and State of Iowa, have invented new and useful AutomobileVacuumCleaners, of which the following is a specification.

.This'invent on a ms to provide a'simple head whereby the suction in theintake manifold of an internal combustion engine may be made available'for cleaning any parts of motor propelledyehicles.

' In the accompanyin drawings Figure '1 is a plane the suction member;Figure 2 is a section on the line 2--2 of Figunel' Figure 3 is asection-on the line 3-3 ofF igureL -Figure4is a plan showing a modifiedform of suction head; and Figure 5 is. a longitudinal section of the 1head shown in Fig. 4.

' In Figure 1, the numeral 6 marks'a suction conduit. 'The conduit 6 isconnected at 7 to the neck 8 of a. foot piece 9 mounted at 10 to thetubular stem 11 of a suction member- 712 comprising a drum-like head 14having an outer wall 15 provided with perforations l6 and including anlmperforate inner wall 17 bounded by a marginal flange 18 within whichis received a back 19 of a brush 20, the body of the brush being markedby the numeral 21 and being made of bristles or any other suitablematerial, securing elements 23 passing through the flange 18 andengaging the back 19 of the brush ,2() to hold the brush in place. Thenumeral 22 marks a stiffener mounted in the foot piece 9 and locatedwithin the stem 11 of the suction member 12, in spaced relation thereto,as 'shown in Figure 3 of the drawings. The stiifener 22 preferably ismade of wire netting, wound 1n a plurality of convolutions, as shown inFigure 3.

About the stifi'ener is placed a porous covering 25 which may be made ofa chamois or any other suitable material.- The stiffener 22 is soconstructed that it will not collapse and cut off the suction, whensuction is created in the conduits and in the tubular stem 11 of themember 12. as hereinafter described.

To all whom it may In practical ooeration, when suction is,- created inthe suction condu t Gsuction will be transmitted to thehe'ad 14 of thesuction member 12 andthe dirt'may be drawn from the cushions, the top orany other part of SI the vehicle, tl1r ougl1 the perforations 16, the

air traversing. the stem; 11 and passing through the porous coverirfg25. The air passes through" the stifi'euel 22 and through the conduit 6and, thus, arthorouglr L cleaning of any part of the vehicle mayeffected, the dirt accumulating in. the stem 11. The foot piece 9together ,with the stiflener 22 and the porous covering 25 may beremoved from the end of the stem 11, N I

whereupon-the dirt may be removed from the stem or handle. If desired,the body 21 of the brush! 20 may be used to loosen dirt, so that thesame may be sucked into' the head 14 through 'the perforationslti. .4

, If "desired recoursemay .be had to the suction head shown in Figures 4and 5. The

suction member alluded to' comprises aftu-j bular neck 26 adapted to beassembled with the conduit 6' and includin a flattened P011. 75.-

tion 27ihavin -an elongated restricted mouth 28. It is o vious thatsuction ;will be created in the member shown in Figures 4' and 5, as inthe specific suction member'delineated in Figures 1 and 2. m

'foraminous material woundinto spiral fornr to fashion convolutionswhich are-in direct contact with each other, the stiffener conformingclosely to the cross section of the filter, the spiral form of thestiffener penmitting it to be made by cutting the constituenkmaterial ofthe stiffener to the desired length and rolling it.

In testimony that I claim foregoing as my own. I have hereto ailixed mysignature in the presence of two witnesses.

EDWARD LINDEN RAY.
